INTRODUCTION

    The days when a PSU could quietly sit in the background are over. ATX 3.1 and PCIe 5.1 have reshaped the expectations around power delivery, pushing manufacturers toward cleaner electrical behavior, safer connectors, and far tighter transient control. These standards didn’t appear out of nowhere, they’re a direct response to the way modern GPUs behave under load, and they set a new baseline for what “proper engineering” looks like in a power supply. For builders, that means fewer surprises, more predictable performance, and long‑term reliability around the 12V‑2x6 interface. The latest YT1000 power supply unit by CPS PcCooler is a 1000‑watt unit designed from the ground up to meet these next‑gen requirements.

    Shenzhen Fluence Technology PLC, established in 2005, is mainly engaged in lithium battery cathode materials, new cooling devices for electronic products and LED industry chain-related businesses, which is recognized as a national high-tech enterprise.

    The YT line of power supply units by CPS PcCooler currently includes 850/1000/12000W output variants all of which are ATX 3.1 & PCIe 5.1 compliant and Cybenetics Platinum certified (up to 93%+ efficiency). Τhe YT1000 model features a single 12V-2x6 power connector, three 6+2 pin PCIe power connectors, single +12V rail (83.3A) capable of delivering 99.9% of the units’ power output (999.6W) and has a total power output of no less than 1119W (220% peak for this model which should place it up to 2.46KW for up to 100ms - once again however this is not something I can test). Other features and specifications include Full-Bridge & LLC Resonant Converter paired with synchronous rectification and DC‑to‑DC regulation (thus allowing the unit to sustain stable voltage output even under rapid load shifts), active PFC, Smart ECO fan mode for the 135mm fan (starts spinning after a specific load), flat embossed Cables and a full array of electrical protections including over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-temperature (OTP), surge protection (SPD) and over-power (OPP). As for warranty once again CPS PcCooler covers their YT line of power supply units with a 10-year limited one.

SPECIFICATIONS AND FEATURES

PACKAGING AND CONTENTS

At the front of the box CPS PcCooler has placed their logo, a large product picture and several certifications.

Moving at the rear we find the unit’s electrical table, available power cables and the specifications table.

As with past models, the unit is placed between two pieces of foam.

Along with the YT1000 power supply unit and its power cord inside the box you’ll also find 5 cable ties, 4 mounting screws, power tester, service & safety manual, quick start guide and the user manual.

THE YT1000 EXTERIOR

CPS PcCooler chose to go with low-profile (flat) embossed power cables for the entire YT line (12V-2x6 cables included).

Measuring 150mm in length, 150mm in width and 86mm in height the YT1000 is a compact high-output model.

The 135mm fluid dynamic bearing fan is placed underneath a nice-looking grille with the company logo next to it.

CPS PcCooler has placed their logo on both sides.

Typically, the electrical table is printed on a large sticker located at the base of the unit.

All 11 power ports at the front of the YT1000 are tagged (12V-2x6 port is also different in color).

At the rear we find the on/off power switch, ECO fan switch and the power port.

THE YT1000 INTERIOR

The YT1000 uses a 135mm FDM fan by Hong Hua rated for speeds up to 2300RPM.

Just like with the YT1200 the OEM behind the YT1000 is the Taiwanese Andyson International.

Primary capacitors are manufactured by Nippon Chemi-Con and are certified for use up to 105 degrees Celsius.

Secondary capacitors are by Rubycon and also certified for use up to 105 degrees.

TEST BED

TESTING METHODOLOGY

     Using a dedicated measurement instrument such as a Chroma or a SunMoon to test power supply units is without doubt the most ideal and accurate way (not to mention the fastest) to do that currently. However, it's certainly not the only way there is and so pretty much anyone can test a power supply unit just by using a test rig. Certainly, limitations do apply and so you can't really push a 1000W power supply to its limits if your system only uses 500W at peak loads and that's why over the years we saved certain hardware components for the purpose of building a dedicated PSU test rig. True it may not be as accurate as the above-mentioned solutions, but it comes really close and is in fact much closer to real world usage. So as always, we ran several games with maximum graphic options enabled at a resolution of 2560x1600 in order to stress every hardware component and increase the overall power demands of the system. The Passmark BurnIn Test was also used to overstress the components in an effort to provide the most accurate results possible. As a final test we also used the latest OCCT software and its dedicated PSU testing suite since it can really bring a power supply to its knees after inside a few minutes.

   Rail stability was checked/measured with the CPUID Hardware monitor and a Metex multimeter which also recorded the system load in idle and in load. As always try to remember that the power consumption numbers listed in the graph are the highest (Peak) ones recorded during the entire duration of the tests and not the average ones. Noise levels coming from the fan were recorded using the high precision HD600 ExTech Sound dBA Meter from the rear of the unit and at a range of no more than 5-10cm. Readings under load are recorded the exact moment we manually switch the fans of all graphics cards from full speed to almost zero, that way the fan of the power supply does not have enough time to slow its RPM and so by doing this we get very accurate noise level readings. Needless to say, in order to get 100% accurate readings, you need to have a noise isolated room for that exact purpose, something which is quite impossible unless you are working inside a real lab (some people use very small noise insulated boxes but due to their size both heat and noise exceed normal levels and so the results can't really be considered to be 100% accurate, nor realistic for that matter). Also do take into account that since all noise measurements take place from just 5-10cm away the final noise levels to reach your ears will be considerably less.

* After well over 10 years of testing PSUs the Intel Core i7-920 CPU of this rig failed and so we replaced it with a Xeon X5660 (we also swapped the GA-X58A-UD7 for the G1. Assassin).

TEST RESULTS

CONCLUSION

    The CPS PcCooler YT1000 lands in a genuinely competitive spot. Its build quality is better than expected for its class, helped by the use of Japanese capacitors and a platform that delivers impressively stable rails, even under aggressive load swings. Electrical efficiency is another strong point, with real‑world results pushing above 93%, putting it comfortably in high‑efficiency territory. But it isn’t without trade‑offs. The Taiwanese OEM behind the platform may raise eyebrows for buyers who prefer more established PSU manufacturers, and the Cybenetics Platinum badge, while credible, just doesn’t carry the same long‑standing recognition as 80 PLUS for some readers. Noise levels at load (especially near the limit) also creep higher than ideal, especially for users chasing near‑silent builds (although to be fair no one gets an 1KW unit to push it to its rated output, recommend grabbing an 1200W or higher output model for such use). Even so, the YT1000 presents a solid, forward‑looking ATX 3.1 option that delivers strong electrical performance where it matters, with only a few considerations depending on how much branding and acoustics matter to you.

    Exactly as with the YT12000 the YT1000 is not widely available and so I can only provide its MSRP (manufacturer’s suggested retail price) which is currently set at USD139.99. This is obviously the single most important drawback the YT line of power supply units currently has and so I hope CPS PcCooler can resolve this fast. Availability aside the YT1000 delivers where it matters most and even though it’s not perfect the Golden Award is in order.
